Well I've changed all my fuel lines now to a new version of Gates Barridgate Greenshield E100 compatible fuel line cleaned out injectors an rail an now my car is running perfect, hopefully fuel lines hold up if not then I'll be going straight for Teflon lines an Speed Flow fittings.Well I hope this may help anyone that seems to think that they may have a similar problem, but I urge for people that may still have some efi hose in the system while using e85 to check on them an replace them.

I would still suggest getting the Injectors professionally cleaned and Flow checked after the amount of Goo that would have gone through them. 1 Link to comment Share on other sites More sharing options...
